INK-ROLL-CLEANING MECHANISM FOR PRINTING-PRESSES.

Application filed October 26, 1905, Serial No. 284,488.

To all whom it may concern.

Be it known that I, CHARLES J. ROBERT- SON, a subject of the King ofEngland, residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Ink-Roll-Cleaning Mechanism for Printing-Presses, of which the following is a specification.

The urgent requirement for speed in the ordinary cylinder printingmachines is now being met in some way by making such presses doublewidth or extremely wide. The advantage of this construction is thatspeed can be obtained, as for a short bed run several forms can beprinted from simultaneously side by side. But in building this style ofmachine it has been found extremely difficult to handle the long andheavy ink rollers necessarily required, such rollers for example, beingin one commercial size of machine, ten feet long and weighing upward ofone hundred pounds. This difficulty is particularly encountered when itis desired to clean or wash the inking rollers which must be done everyday and every time a difierent job of work is to be run. The ordinaryway of cleaning these ink rolls isto take them out of the press and washand clean them outside of the press. This is extremely difficult in thestyle of machine before referred to and takes several men. In order toovercome this difficulty in a simple and expeditious Way, I haveprovided an apparatus by which the inking rollers may be washed 0rcleaned without completely withdrawing them from the machine. To dothis, a carriage frame or tray is provided and is arranged on theprinting machine so that it may be slid laterally thereon. This carriageframe or tray is provided with means for supporting and carrying theinking rollers. The inking rollers are moved longitudinally on themachine and placed in this carriage frame and preferably a lifting orhandling mechanism is provided for this purpose so that each inkingroller can be lifted accurately and expeditiously in and out of thecarriage frame. The carriage frame is preferably arranged on rollers.With this construction, when it is desired to clean the inking rollers,the same are lifted into the carriage frame and the carriage frame ispulled part way out of the machine so that it project-s, say one-thirdSpecification of Letters Patent.

of its distance at one side thereof. With the parts in this posit-ionthe operator can easily wash or clean onehalf of the long inkingrollers. Then this is done, the frame is pulled out the same distance onthe other side of the machine and the other half of the rollers arecleaned. By this construction, therefore, the rollers can be washed orcleaned their entire length without removing the same from the press andwithout having to have the operator reach into the machine very far.

The invention will best be understood in detail by referring to theaccompanying two sheets of drawings forming part of this applicationwherein my invention is illustrated as applied to an ordinarytwo-revolution cylinder printing machine.

Referring to said drawings, Figure 1 is a side elevation of enough of aprinting press to illustrate the application thereto of my invention.Fig. 2 is a partial cross-sectional view illustrating the manipulatingor handling apparatus for the inking rollers, and Figs. 3 and t arepartial cross-sectional views illustrating the operation of the carriageframes.

Referring to the drawings and in detail, A designates the impressioncylinder, B the reciprocating bed, and C the delivery mechanism of anordinary tworevolution cylinder printing machine. The bed is providedwith the usual ink table I upon which ink is deposited by the usualductor roller from an ink fountain F.

11-11 represent the usual spreading rollers which are used to spread theink upon the ink table I. The spreading rollers are arranged in pairsand a distributing roller 12 is arranged on the top of each pair ofspreading rollers. The form inking rollers, arranged in the usual sideframe bearings, are designated by the numerals 131313 and cooperatingwith the form inking rollers are two distributing rollers 14:11. Theparts thus specifically referred to may be arranged in any of theordinary or approved ways.

The improved apparatus for handling the inking rollers is arranged asfollows, and by the term inking rollers I mean any roller or rollersused in the process of inking.

Bolted to the side frames of the machine are brackets 15-15. Detachablysecured on inking rollers.

top of the brackets 15 are guide rails made in the form of invertedT-beams.

T designates the tray or ink roller carriage frame which runs on therails 161(3. This tray T is made up of side pieces 1T-17 and end pieces18l8 the side pieces being connected by a bottom piece 19 preferablymade out of corrugated metal. The end pieces 1S-18 are provided withsuitable notches 180 to receive the journals of the These notches formadditional bearings for the inking rollers at both sides of the machinein which both ends of each roll may be placed. The end pieces of thetray are provided with rollers 2020 which run on the guide rails l6lt5whereby the tray can be pulled laterally either way out of the press.

When it is desired to clean an ink roller or inking rollers, the rolleror rollers which are to be thus treated are placed in the tray, the trayis pulled laterally out of the machine, one-half of the rollers cleanedfrom that side of the printing press and then the tray is slid part wayout of the other side of the machine and the roller or rollers cleanedfrom that side, and then the roller or rollers are put back in position.This can be done very expeditiously with one or two operators.

As the inking rollers are very heavy, it'is desirable to provide themachine with a mechanism whereby the same may be accurately and squarelyplaced in or removed from the tray and easily handled. Such mechanismmay be arranged as follows: A shaft 21 is journaled in brackets in theframe-work. Arms 2222 are secured on the ends of this shaft. Journaledin the ends of these arms is a shaft 23 and secured on this shaft arelong yokes or notched arms 242at. These arms 2at2et are arranged and thenotches in the ends of the arms are so positioned that they may becaused to engage the journals of any one of the inking rollers. The arms24l2t being secured to the shaft 23, are constrained to move in unison.The arms 2424t may be provided with operating handles By thisarrangement, the said notched arms may be caused to engage any one ofthe inking rollers to put the same in or take the same out of the trayas indicated by dotted lines in Fig. 1.

As each inking roller is of considerable weight, it is desirable toprovide a compensating or counter-weighting mechanism. This can beadvantageously done by arrang ing an arm 26 on the shaft 21 andconnecting the same by a powerful spring 27 to a fixed point. As theinking roller has to be lifted out of and into the tray and as when itis done the arms 22 will be raised, the spring 27 will tend to help theaction of lifting the inking roller in and out of the tray. A pin 28 isfitted into the side frames so that when the tray is not to be used, thenotched arms 2+l-2at can be held down out of the my. By thisarrangement, the inking rollers can be easily, accurately, and squarelylifted from operative position and placed in the tray or taken from thetray and placed back in operative position.

By making the carriage frame by which the inking rolls are pulledlaterally out of the machine in the form of a tray or open.

box, the liquid or other material used in cleaning the rolls will dropdown into and be caught in said tray and can be removed or drawn offafter the cleaning has been effected whereby the cleaning can beeffected without daubing or spattering.

The apparatus may be left as a fixture in the machine by leaving therails 16-lt3 bolted to the brackets or the apparatus can be removed whennot in use by pulling the tray out of the machine and if desired,additionally unbolting and removing the guiding rails from the saidbrackets 15.

The details and arrangements herein shown and described may be greatlyvaried by a skilled mechanic without departing from the scope of myinvention as expressed in the claims.

Having thus fully described my invention, what I claim and desire tosecure by Letters-Patent of the United States is 1. The combination of aprinting machine, of inking rollers mounted therein, and a tray or framefitted to slide laterally of the machine in which the inking rollers maybe placed longitudinally, and by means of which the inking rollers maybe drawn laterally out of the machine for cleaning.

2. The combination of a printing machine, of inking rollers mountedtherein, and atray or frame fitted to slide laterally thereon andprovided with notches in which the inking rollers may be temporarilyplaced so that the inking rollers may be drawn laterally out of themachine for cleaning.

3. The combination of a printing machine, of inking rollers mountedtherein, and a boxlike tray fitted to slide laterally on the ma' chinein which the inking rollers may be temporarily placed and by means ofwhich they may be drawn laterally out of the machine for cleaning, thetray or box-like structure being adapted to catch and hold the liquid orother material used in cleaning the rollers.

l. The combination of a printing machine, bearings for holding theinking rollers in operative position, inking rollers mounted therein,and a frame fitted to slide late-rally on the machine in which theinking rollers may be temporarily placed in inoperative position.

5. The combination of a printing machine, bearings for holding theinking rollers in operative position, inking rollers mounted therein,stationary guide rails, and a tray or frame fitted to slide on saidrails in which the inking rollers may be temporarily placed ininoperative position.

6. The combination of a printing press, a carriage frame arranged toslide laterally thereon and to receive and hold the inking rollers, andmeans for assisting in the placement of the inking rollers in saidcarriage frame.

7. The combination of a printing press, an ink roller carrying framearranged to slide laterally thereon, and pivoted arms arranged to assistin handling the ink rollers.

8. The combination of a printing press, an ink roller carrying framearranged to slide laterally thereon, arms or yokes for assisting in thehandling of the inking rollers, and counter-Weighting means for saidarms.

9. The combination in a printing machine of the usual side framebearings, inking rollers arranged therein, additional bearings at bothsides of the machine in which the ends of each inking roller may beplaced, and means whereby said additional bearings may be movedtransversely of the machine.

10. The combination in a printing machine of the usual side framebearings, inking rollers arranged therein, additional bearings at bothsides of the machine in Which the ends of each roller may be placed, andmeans for moving said additional bearings transversely of the machine sothat each roll may be caused to project or rendered accessiblesubstantially half its length alternately at each side of the machine.

11. The combination in a printing machine of the usual side framebearings, inking rollers arranged therein, additional bearings at bothsides of the machine in which the ends of each roller may be placed,means for moving each roll from its usual side frame bearings to theadditional bearings, and means Whereby said additional bearings may bemoved transversely of the machine to make the rolls accessiblesubstantially half of their length alternately from each side of themachine.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing Witnesses.
